Below is a thoughtful taxonomy of the differences between Internet optimists and pessimists from a libertarian group called the The Technology Liberation Front. I particularly like the distinction between the value of "mass collaboration" versus that of "individual effort". While the optimists (I would also include James The Wisdom of Crowds Surowiecki here, of course, and perhaps Jeff Crowdsourcing Howe) have written about the intelligence of the crowd, my team hasn't responded with a book about the intelligence of individuals.
